Abscess

Abscess

definition:
An encapsulated collection of pus in a localized infection with tissue destruction and swelling, or a cavity formed by liquefaction necrosis within solid tissue.

etiology:
Organisms which cause abscess are carried in through direct implantation (e.g. penetrating wound), or spread from other infection sites via blood or lymphatic transport, or breakdown of natural barriers allowing organisms to travel from non-sterile body areas to sterile cavities. Diminished immunity is often a major contributing factor.
